This series adds support for custom DHCP options in passt, enabling network boot (PXE/UEFI HTTP Boot) and arbitrary DHCP option injection.

Two new command-line flags are introduced:

--dhcp-boot URL Sets the boot file URL (DHCP option 67 and the legacy boot file field)

--dhcp-opt CODE,VALUE Sets any DHCP option by numeric code, with type-aware parsing per RFC 2132

The DHCP reply path is extended with option overload support (RFC 2132 option 52), allowing options to overflow into the file and sname fields when the standard options area is full.

Nit: remember to remove this boilerplate that git-publish inserts :)

No, no, that's from git format-patch, I swear (as somebody who doesn't use git-publish).

Oh, my mistake. Same thought applies, though.

Another detail, while at it: for some reason git send-email picked the "chain-reply" style, that is, if you look at this in a threaded email client, patch #1 is a reply to the cover letter (fine, expected) but patch #2 is a reply to patch #1 (not expected), and so on.

That's the --chain-reply-to option for git send-email. You should disable that (for example in gitconfig in case you have it on there) and just use --cover-letter.
